I accidentally got my hands on some aphrodisiacs and decided to test them out on my step sister who lives with me. I secretly gave her one drop every day and gradually noticed something was off. Her body was flushed and sweaty as she wriggled her hips, and she let out sweet sighs whenever I touched her. After a week, my step sister, who had become completely lewd, couldn't stand it anymore and started masturbating. When I barged in, she lost her reason and started sucking on my erect dick. I squeezed her big tits and thrust into her soaking wet pussy, and she revealed her AH face and climaxed repeatedly. It's not over yet, I'll keep going until I turn my nagging step sister into a meat hole...
